Any series2 DirecTV with Tivo will work fine for you. The problems you have read about are with later models of DirecTV receivers. With no current need for HiDef you are in a great position since the DirecTV with Tivo standard definition platform is mature, very high-performing.bulldog12 said:
Since you haven't asked, I take it you have a source to buy one. Hopefully you shouldn't really have to pay much as there must be tens of thousands of them around from Tivo users who have gone on to HiDef.
Edited to add: Sorry I didn't pick up the "DT" (dual tuner) in your post. That's not a "DirecTV with Tivo," as has been pointed out. Personally I think it is a poor choice to use with DirecTV and I would use a "DirecTV with Tivo" series 2 as I discussed.
